Problems solved by technology

[0002] In the production process of lithium batteries, it has to go through coating, rolling, slitting, die-cutting, winding and other processes successively. The positive and negative electrodes of lithium batteries are insulated by separators. If the length exceeds the thickness of the insulating diaphragm, it will cause a short circuit between the positive and negative electrodes of the battery, causing the battery to catch fire, explode and other risks, seriously affecting personal safety. strict testing
[0003] At present, the detection of burrs mainly relies on manual spot checks, that is, it is necessary to intercept a section of the pole piece during the cutting process of the pole piece, and take the intercepted pole piece to the two-dimensional instrument for manual observation, but the detection process is cumbersome and the whole process Manual participation is required, which makes the manual workload heavy

Abstract

The invention provides a burr detection method, device and equipment and a storage medium, and the method comprises the steps: controlling a camera to translate through a translation motor driver after a PLC receives a position coordinate, sent by a data processing module, of a target position on a target pole piece; after receiving a first feedback signal sent by the translation motor driver, enabling the data processing module to collect a first target difference value through a distance measuring sensor and send the first target difference value to the PLC; after receiving the first target difference value, enabling the PLC to control the camera to move through a linear motor driver; after receiving a second feedback signal sent by the linear motor driver, enabling the data processing module to take a target image collected by the camera as input data of a burr detection model to obtain a target label, so that the content of the target label is taken as the category of a target burr at a target position; through the method, the manual workload can be reduced.

Description

technical field [0001] The present application relates to the field of glitch detection, and in particular, to a glitch detection method, device, equipment and storage medium. Background technique [0002] In the production process of lithium batteries, it has to go through coating, rolling, slitting, die-cutting, winding and other processes successively. The positive and negative electrodes of lithium batteries are insulated by separators. If the length exceeds the thickness of the insulating diaphragm, it will cause a short circuit between the positive and negative electrodes of the battery, causing the battery to catch fire, explode and other risks, seriously affecting personal safety. Carry out rigorous testing. [0003] At present, the detection of burrs mainly relies on manual spot checks, that is, it is necessary to intercept a section of the pole piece during the cutting process of the pole piece, and take the intercepted pole piece to the two-dimensional instrument...
